HOISTING AND CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 268,208, dated November 28, 1882.

(No model.)

To all whom it may concern:

Be it known that we, JOSEPH EDWARDS and JAMES R. F. KELLY, both citizens of the United States, residing at Brooklyn, in the eounty'ot' Kings and State of New York, have invented new and useful Improvements in Hoisting and ConveyingApparatus, of which the following is a specification.

This invention relates to a hoisting and conveying apparatus containing a carriage which moves on suitable ways, and is provided with mechanism for raising, lowering, and conveying heavy articles.

The peculiar construction of the apparatus which forms the subject-matter of this applicationispointedoutinthefollowing specification.

In the accompanying drawings, Figure 1' represents a side view of the entire apparatus. Fig. 2 is a side view of the brake mechanism for checking the efl'ect of the driving-power on a larger scale than the previous figure. Fig. 3 is a side view of the drums which carry the rope for transmitting motion to the carriage and to the hoisting-drums. Fig.4is a plan or top view of the same. Fig. 5 is a side view of the carriage. Fig. 6 is a plan or top view of the same. Fig. 7 is alongitudinal vertical section of the same in the plane .10 00, Figs. 6 and 8, showing the brake mechanism. Fig. 8 is a plan or top view of the same.

Similar letters indicate corresponding parts.

In the drawings, the letter A, Fig. 1, designates a structure or store-house, which contains the hoisting apparatus, and which may be erected on a dock, if the hoisting apparatus is to be used for loading and unloading vessels,

or which may be situated in any convenient position,ascircumstances willdictate. In this structure is firmly secured a track, B, at a convenient height above the floor or ground, and on this track is placed the hoisting and conveying carriage O. (Best seen in Figs.5, 6, 7, and 8.) This carriage is provided with four wheels, to a b b, which run on he track B, and it (the carriage) is drawn along on the track several times round two drums, d c, Fig. 5,

and which connects with the driving mechanism,aswillbehereinafterexplained. Thedrum dis firmly mounted on a shaft,f, and on this shaft are also mounted two friction wheels, gg,

which serve to transmit the motion of the drum d to the hoisting-drums It 1'. These hoisting-drums are mounted firmly on shafts h 2', respectively, and with each of the drums are firmly connected two friction-wheels, k W, respectively, in such a position that they can be thrown in or out of gear with the frictionwheels 9 g by the following mechanism: The shafts h i are mounted in eccentric boxes If 2' which can be turned in their beari n gs by means of levers 13 The levers It, one on each side of the carriage, are connected by rods k with levers h", mounted on a rock-shaft, h and they are also connected by rods h with levers h, mounted on a rock-shaft, h one of the levers [L9 being elongated so as to form a handlever, which in the following description will be designated the liand-leverh fl In the same manner the levers z -oneon each side of the carriage-a-re connected by rods with levers i mounted on a rock-shaft, i and they are also connected by rods 17 with levers t9, mounted on a rock-shaft, 6 one of the levers i being elongated so as to form a hand-lever, which in the following description is designated the hand-lever i When the hand-levers h t are in the position shown in Figs. 5 and fithefriction wheels h 2' are out of gear with the'friction-wheels g, and no motion is transmitted from the drum d to either of the hoisting-drums; but if the hand-lever h is drawn outward in the direction of the arrow marked near it in Fig. 5 the friction-wheels h are thrown in gear with the friction-wheelsg g, and, consequently receive motion from the drum (1. The hand-levers h9 i are operated by men occupying the seats D D but in some cases it is desirable that the man occupying one of the seats-say the seat D-shall be able to throw both hoisting-drums in or out of gear with the moving drum d. For this purpose I have mounted loosely on the rock-shatt h an additional hand-lever, 43 9, which connects by a rod, 6 with a lever, 1' mounted on the rock-shaft '5 (See Figs. 5 also 6.) The man occupying the seat D can throw the friction-wheels h in gear with the moving drum d by drawing the hand-lever k outward, and by pushing in the additional hand-lever 01 he can throw the friction-wheels i in gear with the moving drum. By similar means the friction-wheels 7L2 may be operated from the seat D. The drum h is provided with a hoisting-rope, h", one end of which is firmly secured to a bolt, h, Fig. 6, while its 7 other end is fastened to the drum h, so that by revolving this drum in the direction of arrow 1*, Fig. 5, the rope is wound up, and by revolving the drum in the opposite direction the hoisting-rope is unwound. In the same manner a rope, W, is fastened at one end to the drum iand at its opposite end to a bolt, i so that when the drum 1' is revolved in the direction of arrow 2*, Fig. 5, the hoisting-rope 2' is woundup, and vice versa. The articles to be raised or lowered are secured to pulleyblocks It i, which are placed into the bights of the hoisting-ropes h 2', Fig. 5.

On the rock-shafts h i are mounted brakeshoes h 11", respectively, (see Figs. 5 and 5*,) in such position that when the hand-lever h is moved so as to throw the friction-wheel if out of gear with the movingdrum d the brakeshoes h" are brought to bear upon the surfaces of the friction-wheels 71. and if the handlever i is moved so as to throw the frictionwheels i out of gear with the moving drum d the brake-shoes i are applied to the surfaces of these friction-wheels. By means of this brake mechanism the weights suspended from the hoisting-ropes h i can be maintained in an elevated position or permitted to descend slowly. The brake-shoes are mounted on eccentric-bearings h i", so that they receive a positive motion in either direction it the shafts h i are turned.

In order to draw the carriage along on the track B, it is necessary to hold the drum at so that it cannot revolve, and if the endless'rope 0 moves in the direction of arrow 1, Figs. and 6,'the carriage will be drawn along in the same direction, and vice versa. During the time, however, when goods are to be raised or lowered, it is requisite that the carriage shall remain stationary. For these purposes a compound brake mechanism is applied, which is best seen in Figs. 7 and 8, and which will now be described.

On one side of the moving drum dis firmly secured a pulley, d, Figs. 6 and 7, and round this pulley extends a flexible strap, d Fig. 7, the ends of which are fastened'one to one and the other to the other arm of a bell-crank lever, d. which is firmly mounted on a rockshaft, cl, that has its hearings in the frame of the carriage O.

On the rock-shaft d are mounted two levers, d Fig. 8, which connect by rods 01 with the upper ends of levers b, which swing on pivots b secured in brackets attached to the brake-head b which carries the brake-shoes 7 the shaft (1* is turned, the strap d releases the pulley d, and'the brakes a b are applied to the wheels a b, the carriageis held stationary on the track B, and the drum d is free to revolve. If the brake-lever E ismoved in the direction opposite to said arrow, the brakes a b are taken off, and the strap d is drawn up tight round the pulley d, the drum d is prevented from turning, and the carriage is free to follow the action of the endless rope 0.

By referring to Fig. 5 it will be seen that the brake-lever E is in position to be operated by the man occupying the seat D. If desired, a similar brake-lever may be applied near the opposite end of the carriage, so that the brake mechanism can also be controlled by the man occupying the seat D.

The endless rope 0 receives its motion by the mechanism represented in Figs. 1, 2, 3, and 4.

The shaft k, Fig. 1, is the driving-shaft, to which motion is imparted by a steam-engine or other source of power. From this drivingshaft motion is transmitted to the countershat't 1, preferably by means of a chain and chain-wheels, and on the shaft Z is mounted a chain-wheel, I, from which motion is transmitted by a chain, 1 to a chain-wheel, m mounted firmly on a counter-shaft, m, Figs. 3 and 4. This shaft is geared together with a counter-shaft, n, and both these shafts are mounted in eccentric boxes m a, respectively, as seen in Fig. 3.

On each of the eccentric boxes is firmly mounted a lever, m and these levers connect by rods n with levers 02, mounted on the eccentric-boxes n. The levers it connect by rods n with levers o, mounted on a rock-shaft, 0, and one of the levers 0 is extended so as to form a hand-lever, which hereinafter will be termed the hand-lever 0'.

On the shaft m is firmly mounted a frictiongear, m and a similar friction-gear, n is mounted on the shaft n. If the hand-lever 0 is brought into the position shown in Fig. 3, the friction-wheel n is thrown in gear and the friction-wheel m is thrown out of gear with a friction-gear, 10 which is firmly mounted on a shaft,p; but if the hand-lever 0 is moved inward to the position indicated by the line 0* the iriction-wheel m is thrown in gear and the friction-wheel if out of gear with the Wheelp and if the hand-lever 0 is brought in a vertical position (indicated by line 0, Fig. 3) both friction-wheels m n are thrown out of gear.

On the shaft 1) is mounted a drum, 1), which 'is situated in a vertical plane passingthroughthe middle line of the track B, or nearly so, while the friction-gearsp m M, the chain-wheel m and the chain Z are so placed that these parts do not interfere with the motion of the endless ropec and of the carriage O. (See Fig. 4.) The endless rope cis wound several times round the drump and round a secondary drum, q, thence over a series of guiderollers, c, Fig. l, to and over pulleys 0 c thence to and round 55 s. 2 and 4. The ends of the strap 19 ar the drums de in the carriage O, thence under I and around a pulley, c and over pulley 0 back to the drum 1; and both these drumsare provided with a series of circular grooves for the reception of the rope. If the rope is wound round a single drum only,and arevolvingmotion is imparted to this drum, it happens that the drum revolves without imparting motion to the rope, and we havetherefore found it nee-- essary to employ two drums, p q, whereby, even if the rope is comparatively slack, it is not liable to remain stationary as long as the drum revolves. The employment of the two drums, however, enables us to keep the rope taut in the following manner: The drum q is mounted on'a shaft, q, and this shaft has its hearings in boxes g which can be moved in guideways g and are exposed to the action of set-sciewsq. These set-screws are tapped into slides (1 which are fitted between the guideways g and are provided at their bottom with ledges q, Fig. 3, which catch in recesses g in the bottoms of the guideways 1 as shown more particularly in Fig. 3*. Bolts g serve to secure the slides in the required position, and the boxes g are fastened in the guideways by bolts The object of this arrangement is to take up the slack of the endless rope o and to keep the same taut under all circumstances; and since this endless rope, on account of its great length, is liable to stretch considerably, the set-screws q, if tapped in fixed supports, would not be sufficient to accomplish the (lesired'object; but by means of the slides g the set-screws can be always adjusted in such a position that they can be brought to act upon the boxes g of the shaft q, and the endless rope can be held taut. At the same time, by means of the ledges g recesses g and bolts 1 the slides are retained firmly in the required position.

The friction wheels 711. 12 receiving their [110- tiondirectfrom the driving-power, revolve continuously, and if either of the friction-wheels is thrown in gear with the friction-wheel 19 motion is transmitted to the drum 1;, to the endless rope 0, and through this endless rope to the hoisting mechanism in the carriage O. In order to be able to'cheek the motion of the endless rope 0 immediately, when both the friction-wheels m n are thrown out of gear with i the friction-wheel 19 a brake mechanism is ap plied, which consists of a strap, p embracing a pulley, 19, that is firmly secured to the drum secured to a disk, r, on opposite sides of the center of the shaft 1", on which said disk is mounted, so that by turning this shaft in one direction the strap releases the pulley p and drum-19', and by turning said shaft in the opposite direction the strap hugs the pulley p and checks the motion of the drum p and endless rope c.

On the shaft r is firmly mounted a doublearmed lever, W, on one end of which is secured a weight, 14, while on its other end is fastened acurved saddle, 1". When the weight 1' is raised to the position shown in Fig. 2 the strap f releases thepulley p; but when the weight 1' is permitted to drop the strap 12 is drawn up tight against the pulley p. The position of the Weight 1" is governed by cams s 8 which are secured on the end of a rockshaft, 8, at about right angles toward each other. t

On the rock-shaft s is mounted a pulley, s, on which are secured the ends of a rope, 8 which, after having been wound once or more times round said pulley, passes over guidepulleys 8 (see Fig. 1) and runs in close proximity to-the carriage C, so that itcan be reached by the men occupying the seats D D. It the carriage moves in the track B in the direction of arrow 1, and it is desired to stopits motion, one of the men on the seats D D pulls the rope s in the direction of the arrow marked near said rope in Figs. 2 and 4. As the rockshaft turns in the direction of arrow, Fig. 2, the cam s releases the saddle r, the weight r tui'ns the shaft 1', and the strap 12 hugs the pulley 11. At the same time-thefriction-wheel n is thrown out of gear with the friction-' wheel 17 by the following mechanism:

On the shaft .9 is mounted a pulley, t, on which is secured a rope, t, Fig. 4, which extends round guide-pnlleys t and is secured to the hand-lever 0. When the rope s is pulled in the direction of the arrows the pulleyt turns, so as to move the rope t in the direction of the arrow, and the hand-lever 0 is moved to the position indicated by the line 0, Fig. 3,-and the friction-wheel n is thrown outof gear with the friction-wheelp If the rope s is drawn still farther, the cam s strikes the saddle 1, the weight 1' is raised, and the strap 113 releases the pulley p At the same time the hand-lever 0' is moved to the position indicated by the line 0*, Fig. 3, the friction-wheel m is thrown in gear with the friction-wheel 11", and the motion of the endless rope cis reversed. From this description it will be seen that the rope .9 serves to check, stop, and reverse the motion of the endless rope c, and that said rope s can be controlled by the men occupying the seats on the carriage G, or by a man stationed at the hand leverofltor if this handlever is moved its movement is transmitted to the brake-lever r". The principal object of the rope 8 however, is to enable the men 00- cupying the seats on the carriage G to reverse the motion of the endless rope c and of the carriage, for they have other means to stop and to check the motion of the carriage by means of the levers h i and the brake-lever E, as already described. From this description it will be seen that the men occupyingthe sea ts on the carriage are enabled to move the carriage to any part of the track B, and to impart motion to either of the hoisting-drums hi in either direction, so that they can raise a cask or other article by means of the hoisting-ropes h i then move the carriage on the track B, and finally lower the casks into the hold of the vessel, or vice versa.

4 ecaeos By referring to Fig. 10f thedrawingsit will l be seen that the track B is extended beyond. the end of the structure or store-house A a sufficient distance to allow of moving the carriage over the hatchway of a vessel,or over a truck or wagon which may be intended to deliver or receive the goods. The extension of the track 13 is hinged, so that it can be turned up in a vertical direction,and is not in the way of bringing a vessel close up to the end of the store-house.

It is obvious that the endless rope and the driving mechanism which we have designed can be applied for other purposes besides the diiving of the carriage O.

In place of the friction-gears, cog-wheels may be substituted, which are connected to their respective shafts by friction-couplings.
